Abstract

PURPOSE:To extremely reduce distribution cost and to inexpensively provide consumers with fresh live fishes, by catching live fishes, etc. tamed at low temperature with fibrous supporters in a swimming attitude, storing the fishes in a mist constant temperature chamber in a specific atmosphere and transporting the fishes. CONSTITUTION:Live fishes, etc. produced in a sea area, before transportation, are tamed in a water tank capable of controlling temperature, feed is stopped, temperature of natural sea water is successively lowered in a range of 5 deg.C to 10 deg.C to suppress activity, the fishes are caught with fibrous supporters 2 in a swimming attitude as it is in sea water and stored in a mist constant temperature chamber 1. Then mist is released from nozzles in the chamber 1 through a cooler 3, a water supply tank 4 to be used for generating mist and a pressure pump 5 via a water feed pipe 7 to the mist constant temperature chamber 1, oxygen is released from an oxygen bomb 6 to a nozzle of a gas pipe 8, an atmosphere in the chamber is maintained at low temperature at high humidity and the fishes are transported.

Description

[Detailed Description of the Invention] A) Industrial Application Field The method for transporting live fish, etc. according to the present invention relates to the practical application of transport technology to provide fresh live fish to consumers at low prices, especially in the distribution of live fish. It is.

口）Conventional technology Consumer needs for marine fish and shellfish are changing from conventional fresh fish distribution to live fish distribution, and with the conventional transport method using aquariums, live fish can only be transported by approximately 10% of the aquarium water volume in a shipping container. It is extremely inefficient and difficult to manage water circulation, filtration, temperature, etc., and has a large impact on consumption prices.

C) Problems to be solved by the invention As research into the ecology of fishes progressed, it was discovered that the carp respiration of fish not only functions underwater, but also that life can be sustained if moisture is mist-formed and oxygen is sufficiently present. . Furthermore, by lowering the water temperature, the fish's metabolism is suppressed and oxygen consumption is minimized to solve the problem of transporting live fish.

2) Means for solving the problem As a means of transporting live fish, etc., a mist constant temperature storage for transport is equipped with a cooler to maintain the temperature at a low temperature of 10°C, and water is supplied in the form of a mist along with oxygen.

Live fish housed in the housing space in a low temperature, high humidity, and oxygen-containing atmosphere of about 10° C. can fully survive. However, for live fish, etc., the temperature should be lowered from the room-temperature tank by 5°C in an acclimatization tank, and food should be stopped during that time to suppress the live fish's metabolism, and then captured using a fibrous supporter that maintains the fish's swimming posture. - Stored in a constant temperature warehouse.

E) Function The method for transporting live fish, etc. according to the present invention differs from conventional live fish transport in that they are captured and kept in a thermostatic chamber with fiber supports. According to this invention, live fish, etc. produced in the sea area are placed in an acclimatization tank where the water temperature can be adjusted before being transported, and the natural surface water temperature is gradually lowered to 10°C within a range of 5°C. (2) Capture the fish in seawater with a fibrous supporter and (1) Suspend and store it in a mist constant temperature storage. It is something to do. This (1) constant temperature mist storage is used for cooling the inside of the storage. (3) Used to generate a mistake between the cooler and water (4)
It consists of a water tank, (5) a pressurizing pump, and (6) an oxygen cylinder, and (7) mist is released from a nozzle inside the warehouse through a water distribution pipe, and (8) oxygen is released from a nozzle on a gas pipe. . As mentioned above, (1) the mist constant temperature warehouse is (3)
) The water temperature is maintained at 10°C, which is the same as the water temperature in the acclimatization tank, using a cooler, and the water necessary for the fish to breathe is supplied in the form of mist along with oxygen, thereby preserving the environment in which the fish can survive.

Next, (1) a report on the results of an experiment conducted using live sea bream in a Misl-thermal storage is presented. (9) At the production area, live sea bream that has been fed for about 12 hours in a livestock nursery (10) is picked up in a live fish boat and kept on land at a natural surface water temperature of 22°C in (11) an acclimatization tank. If you allow the sea bream to acclimatize to a temperature drop of 10°C over 8 hours within the 3-hour temperature range of 5°C, the sea bream will become sluggish, so keep it in the aquarium (2).
3) Keep the temperature inside the refrigerator at 10℃ with a cooler (4) Pressure from the water tank (5) Pressurize A pump ejects 0.5 hours per hour in the form of a mist, and at the same time (6) 100 tons of oxygen, about 3% of the capacity, is released from an oxygen cylinder and transported to the consumption area, Tokyo's Tsukiji Fish Market, for a 24-hour trial. After (1
3) The water temperature of the receiving tank was adjusted to 10°C in advance and the number of surviving sea bream was confirmed, and the total number of sea bream was 100.
% survival was confirmed.

f) Effects of the invention As mentioned above, the present invention relates to a method of transporting live fish, etc., which is significantly different from the conventional aquarium transport method, and reduces the cost of chorus distribution, which increases the market share of live fish, etc. This greatly contributes to the reduction.

Taking this experimental transportation method as an example, in the conventional aquarium transportation method, the actual weight of fish in a 4-ton trunk and a 3m' aquarium is approximately 10%, or 300 kg;
A transport energy of 3,300 kg is required. According to the transportation method of the present invention, the volume of the mist constant temperature storage is 3rn'
With this, it is possible to transport approximately 20% of the eoOKg of fish, and the actual load is I (00 kg compared to the conventional 115), which saves transportation energy and halves the freight cost for each fish, reducing overall distribution costs. is enormous.
